Math Typesetting

The Stack theme supports rendering mathematical notation using KaTeX.

Enabling KaTeX

To enable KaTeX for a specific post, include math: true in the post’s frontmatter:

1
2
3
4
---
title: "My Math Post"
math: true
---

To enable KaTeX for all posts, set article.math to true in your site configuration (params.yaml or params.toml):

1
2
article:
    math: true

You can include math inline by wrapping the expression in single dollar signs $.

For example: $ \varphi = \dfrac{1+\sqrt5}{2}= 1.6180339887… $ renders as $ \varphi = \dfrac{1+\sqrt5}{2}= 1.6180339887… $

For larger equations, use double dollar signs $$ to create a math block.

$$ \varphi = 1+\frac{1} {1+\frac{1} {1+\frac{1} {1+\cdots} } } $$

$$ f(a) = \frac{1}{2\pi i} \oint_\gamma \frac{f(z)}{z-a} dz $$
